5-Hydroxytryptamine Receptors Imaging Analysis

5-Hydroxytryptamine Receptors Imaging Analysis

Serotonin is an important neurotransmitter, which is involved in regulating a wide range of physiological functions. The disorder of serotonin may cause a variety of psychiatric diseases, such as depression, schizophrenia, bipolar disorder, migraine and so on. 5-hydroxytryptamine receptor is a protein located on the cell membrane. Endogenous ligands, drug molecules and lipids are very important for the regulation and maintenance of its function. The physiological function of serotonin is mediated by more than a dozen 5-hydroxytryptamine receptors. Therefore, imaging analysis of the molecular structure and functional mechanism of 5-hydroxytryptamine receptors will bring new hope for the treatment of psychiatric diseases.

5-Hydroxytryptamine Receptors Imaging Analysis

In the past, scientists had little understanding of the fine structure of the serotonin receptor, making the development of new targeted drugs difficult. Co-immunoprecipitation, resonance energy transfer (RET) and bimolecular fluorescence complementation (BiFC) are commonly used methods to study the structure of 5-hydroxytryptamine receptor dimers, tetramers and higher-order oligomers. Co-immunoprecipitation requires solubilized proteins and cannot be applied to live cells, RET and BiFC can be applied to live cells, but they cannot directly measure protein-protein interactions. In order to develop more effective and less toxic therapeutic drugs, single-particle cryo-electron microscopy and fluorescence correlation spectroscopy are used to study the structure of 5-hydroxytryptamine receptors.

CD BioSciences has been committed to the development of fluorescent dyes and imaging technology for many years. We can study the structures of 5-hydroxytryptamine receptor-ligand complexes and 5-hydroxytryptamine receptor dimers by single particle cryo-electron microscopy, confocal microscopy and fluorescence correlation spectroscopy techniques, providing a theoretical basis for drug development targeting the 5-hydroxytryptamine receptor.
